My Nraas and other Sims 3 Settings on Mac

When I play, I’m a little bit ocd that the game should play so smooth all the way. As much as I wanted to, but the game just doesn’t work smoothly when I use mac. I have to accept that sims 3 is not mac native and will never be that stable during gameplay. But anyway, I still tried to find solutions to these issues. Thankfully, nraas is there and there’s just so many sims 3 settings that you can customize so that your game runs smoothly, while you can truly enjoy the game. So today, I’d like to share the settings I made to all the nraas mods installed on my game, and also share some other things to do on mac to make the gameplay entertaining.

Sims 3 isn’t really enjoyable whenever you find that all the neighbors of your precious sim are getting older, and are dying. You don’t want to have a lonely sims town! So I decided to search for mods that have a story progression. I’ve read a lot from forums, and thankfully I was able to solve all my sims errors on my mac even with this heavy mod story progression from nraas.

Screenshots will be provided so that it would be easier to locate the options. 🙂 I really hope you find this post helpful.

Oh, before anything else, you should see my hardware. It’s not a gaming laptop, it’s an artist’s laptop 🙂

And also, I have the following expansion packs and store items:

  • generations
  • ambitions
  • island paradise
  • university life
  • late night
  • seasons
  • pets

I also have:

  • Roaring Heights
  • Dragon Valley
  • Monte Vista
  • Lucky palms

Table of Contents (Nraas Sims 3 Settings and more)

Okay, here’s a simple list of what I’ll be talking about.

  • I’ll share all the nraas mods I am using that will totally help reduce lag.
  • Simple ways to clear cache files.
  • And the use of wineskin!


Okay for nraas, I’ve got mastercontroller, story progression, overwatch, traffic, register and go here. If they are properly installed on your game, you should see these things when you click a computer>nraas or city hall>nraas

Nraas Mastercontroller

Alright, so nraas mastercontroller is basically a super strong and powerful mod for controlling almost everything in your town. You can kill a sim using this mod, or even add a roommate with this mod without doing too much work. This is also the mod I use to reset all objects in town, which really helps reduce lag and corrupt game. Screen Shot 2015-05-14 at 1.52.11 pm


This is what you’ll see when you click nraas mastercontroller. Demographics will just basically show you the demographics, and even export data files about your town to your hard drive, although I wasn’t sure if this works because I’ve never seen a saved/exported file on my documents before. You’ll see all the options available when you go to but for now, I’ll just tell you what really helps in your mac!

The best thing to do before you start playing the new town, is to reset everything. Simply click “town” then “reset everything”. After that, it would be best to save the game first, before you hit play. This will really help reset those bugged sims and other objects in town, as well as those that are trapped or something somewhere.


Nraas Story Progression

Yes, my intro says it all. I love story progression because this mod helps make the town alive. One time I was playing sims, 4th generation, and I couldn’t find many sims around town anymore because most of them are already dead! It’s just sad that I have to go to edit town again, and make new households, that’s just sad. This mod makes the townies have a real life, find a job, get married, have babies and all things necessary to survive and have fun! So I think this mod is really needed whenever I play sims.

But, the downside for this mod is the ultra super extreme LAG! It crashes the game really bad. The best way to fix it is to cool down the settings.

If you go to general options, you’ll see the speed of the town progression and you can change it to slow, or default, or snail and etc. I used the snail speed, just so the game won’t crash while there is a good story progression in my town. Screen Shot 2015-05-14 at 1.53.11 pm

If you also ever get annoyed with the notifications, you can change them from the general options menu too. The “all stories” option is where you can adjust what stories you’ll be notified for. You can choose relatives only by clicking “blood” which is what I usually choose, or friends, or romantic, or etc. You get the idea.

Another option to lessen the lag is to lessen the population! Look for “options:sims”. And you’ll see maximum residents allowed in your town. You won’t see this option if your story progression is not enabled. I had that problem before 🙂 so just want to make sure everything’s clear.

I always choose the maximum residents to only 100, anyway, I don’t play all of them. Some are just decorations around town. From this option you can also find something like “town occult ratio”. You can adjust how many percentage will there be vampires, zombies or fairies around your town. Lessen them to what you feel your laptop can carry. There are so many other options in there to explore, but for now, these are the things that I changed.

Overwatch, Traffic, Go Here

For these other nraas mods, I leave them there without changing their settings. They always do their task while I play, and everything runs smoothly.

Overwatch – This mod’s purview is the correction of persistent or recurring errors produced by the Core game or other mods. I love this mod because it fixes some bugs on my game.

Traffic – This mod’s purview is the alteration of the EA Traffic Manager, which controls the food truck and fake taxis added by

Go Here – This mod’s purview is routing interactions, namely the “Go Here” and “Visit Lot” interactions used either autonomously or via user-direction.

These mods do their jobs great, so I don’t have to edit the settings in there after installing.


Register – This mod’s purview is the manipulation of the service and role sims in your town. This mod really is working. I love it whenever mixologists, and other service sims are coming over the town. I also have the option to control the wild animals using this mod. You’ll immediately see the option “animal control” and then adjust how many animals are allowed in your town. This really helps a bunch! 🙂


Clear Cache Files

Okay, this one’s been a great help for me eversince! Clearing cache, or in other words, cleaning out bad stuff, removing ugly stuff!

First thing to remove, the cache files from your previous gameplay. All these files can be found under electronic arts>the sims 3> folder. Delete the files sims3logs.xml, all scripterror….xml (unless you want to use these for debugging purposes), and the 5 basic cache files – scrictcache.package, compositorcache.package, simcompositorcache.package,caspartcache.package, and socialcache.package. These files are safe to remove.

Next files to remove are the files under “worldcaches” folder. These are simply the cache files from the world you are playing with. You should remove these, these are heavy files!Screen Shot 2015-05-14 at 4.02.39 pm



Another set of files to delete, are the bad saved files. When you see a folder under “saves” folder that has .bad on it’s filename, remove it. It is usually caused by exception raised, or error code 12 which are just corrupt files or memory error. I never had any experience of fixing the error code 12 and exception raised eversince. So it would be best to save your game every simday. It is highly recommended to save it!

For the featuredItems folder, it has a ton of heavy photos of featured items, and it annoys me that it’s too heavy everytime I open the game. So I made sure that this folder will never have photos in it anymore by changing the folder’s settings. Right click the folder, get info, and then go to sharing & permissions, and change all privilege to “Read only”. This is to make sure that the game won’t place a bunch of useless photos in this folder.

Okay, proceed to clearing some other cache files. You can delete the files under “thumbnails” folder, they won’t hurt your game. I don’t know their use anyway, although I am sure it’s fine to remove them since I never got errors everytime I play, and also, these files always comes back to this folder whenever I open the game. 🙂

Lastly, this folder “DCBackup”. Based on forums, this folder contains cache files of store items you’ve used in gameplay. It’s safe to remove ALL the files EXCEPT the ccmerged.package! 🙂 I removed this file once, and all my store items are gone. I had to reinstall the whole sims 3 game to make store items work again.

I think I’ve covered all the clear cache stuff for sims 3. Now I’ll go to the last part, the wineskin!



This has changed so much of my game! Download the wineskin file here

Okay, so here’s the great thing about wineskin. It somehow tricks mac to make it seem to run on a windows OS while on gameplay. All you have to do is copy the wineskin file to the sims 3 app. Just right click on sims 3, show package contents…

Screen Shot 2015-05-14 at 4.18.05 pm


Go to contents, macOS folder, and add the wineskin to the macOS folder.


Screen Shot 2015-05-14 at 4.18.13 pm


I don’t know why or how, but I guess it helps the game run on mac like it’s on windows. Eversince I added wineskin on my game, I seldom get error or crashing after a LONG hours of gameplay.

So that would be all of the things that I can recommend when you play sims 3 on mac. Sims 3 is not really stable on mac, so people get so sad playing on mac that they really have to find solutions to have it run on their mac. I don’t know with other mac computers, but these are the sims 3 settings that I made on my mac to make everything work. I guess it’s also best to remove useless mods, and not install too much mods on your game. People say that mods can really break your sims app.

I’ve also read in some posts that you can still run all sims expansion packs on this mac well, as long as you don’t have mods. Another great advice from other mac simmers too is to install vmware, parallel desktop, or bootcamp to your mac. I think it’s fine, but it’s different if you play it straight from mac. It’s enjoyable when I play it on mac, it loads faster than in a virtual windows.

I’ve learned so much reading forums and googling, there are so many resources too from thesims3 forum (a mac user for a long time), modthesims, and thesimsresource. 

I hope you find this helpful, and at least solved some of your sims 3 errors on mac. Just comment below if  you have tips and tricks in using sims 3 on mac! Thanks.
